Water molecules diffuse through the cell membrane through aquaporins. How are these proteins helpful in osmosis?

Aquaporins increase the rate of osmosis which is generally slow due to the polarity of water molecule.

Osmosis is a type of cellular transport in which water moves from a region its high concentration to its low concentration through a semipermeable membrane.

Aquaporins are protein channels that allow transport of only water molecules through cell membrane during osmosis.

Aquaporins increase the rate of osmosis which is generally slow due to the polarity of water molecule.

Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis

Explanation:

Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.

Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.
